Rainley began with a simple realization: water, essential for life, was quietly affecting personal health. Living in a fast-paced city, we noticed how tap water caused dryness, irritation, and dullness in our skin, hair, and nails, even with pricey skincare and haircare products.

Existing shower filters didn’t help. They provided no clear way to measure their effectiveness, and the common advice to change them every three months overlooked how water quality varies across different locations. Frustrated by these limitations, we decided to take action. This inspired the creation of Rainley, with a mission to make water care accessible, effective, and transparent.
